Abstract

A data processing apparatus stops a supply of data to a buffer when the buffer becomes full, and thereafter performs processing such as moving to a low-power mode and switching execution tasks. The data processing apparatus then reverts from the low-power mode and resumes execution of a task for supplying data to the buffer when a predetermined reversion condition is satisfied. The predetermined reversion condition is that, for example, processing with respect to data in a predetermined data cluster is completed, a predetermined time period has elapsed, or a cycle handler notifies an event occurrence.

Description

[0001] This application is based on Patent Application Nos.2006-225710 and 2005-251179 filed in Japan, the content of which is hereby incorporated by reference. BACKGROUND OF INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a data processing apparatus for reading data from a recording medium etc., supplying the read data to a buffer, reading the supplied data from the buffer, and processing the read data, and in particular to technology for controlling operations of the data processing apparatus while waiting for free space in the buffer.

[0004] 2. Related Art

[0005] When data processing speeds and data transfer speeds vary between different devices, data processing apparatuses are widely used to absorb the difference in these speeds by supplying data to and reading data from a buffer.

[0006] In conventional data processing apparatuses, a free space status of the buffer is observed while controlling the supply of data to the buffer such that data no...
